"Buying from Diesel Ops is the best online purchase i have made."

I have bought many parts for my pickup, snowmobiles, bikes, etc. My experiences have ranged from absolutely awful to excellent. Most places seem to have their positives and negatives. My experience with Diesel Ops has been excellent. I contacted them about buying a fass lift pump and was advised on which one would work the best for me. They took the time to make sure i was getting the absolute best product for my pickup (which wasn't the most expensive). After deciding which pump to get the order was placed at an excellent price and was shipped and to my house in two days. I will be buying all my future parts through diesel ops.

"Number one company I ever delt with!"

When I order a part I expect it to be exactly like described and I want it ASAP! We'll that's exsactly what I got. A great product and had it the next day. No hassle no problems. Can't thank you enough. Will be back for more.

"OUTSTANDING!"

The service that I received was second to none.One of the owners called me back about the innercooler for my duramax and completely answered all my questions.He told me if I had any concerns to email him after hours and leave a contact number and he would call me back.Their customer care is what will have me ordering again.You will not go wrong with this company

"Excellent company."

Great service and communication

"the best customer service period"

I was ordering a pretty big list of parts and had a few questions JD went out of his way to make sure all my questions were answered and he was able to get all the parts on my list. My parts arrived very fast and I got a great deal along with the diesel ops cash they offer. All in all this was a great transaction and they will be getting all my business from now on.

"Great lube"

Good product that does exactly what it's supposed to

"Great Customer Service"

I'd just like to say thank you for the great customer service and prompt response. I had an issue when ordering and contacted Dieselops about it and they had my order and issue fixed promptly and on a Sunday no less. Couldn't be happier and look forward to doing more business with them in the future.
